Licuefacción

The video explains soil liquefaction, a process where solid soil behaves like a liquid during an earthquake. It occurs in moist sandy soils when water trapped between sand grains escapes due to ground shaking. This causes the soil to lose its structure and flow like mud, damaging infrastructure. The video also highlights the Kobe earthquake as an example and mentions ongoing engineering efforts to prevent such occurrences in the future.
